From the Huffington Post: Billionaire Republican Meg Whitman reported Monday that she has spent more than $99 million in her quest to become California's governor, while Democrat Jerry Brown is saving money for what could become the most expensive gubernatorial contest in American history.

Brown, who faced no serious challenger in the Democratic primary, has spent just $450,000 on his race to date, although the number climbs to $774,000 once donated services are included. Whitman's figure jumps to $100.3 million when such services are included.

A poll released last week by the Public Policy Institute of California found the candidates about even among likely voters, with 37 percent backing Brown and 34 percent favoring Whitman. A quarter of respondents were still undecided.
